12 Volt Wiring Question Re: Lighting

[WildWG]

I want to install a swatch or pendant lamp that will hang down over the dining table in our 2619. I intend to install a 12 volt socket in the ceiling where the lamp can be plugged in. I have seen advertised, 12 volt light bulbs that screw into regular 120 volt lamp fixtures. Can I just use a 120 volt lamp fixture without any modifications, such as different wiring? I have searched the internet for a suitable 12 volt lamp and can find none. Besides, the RV lamps I have seen are in the $ 75.00 range, more than I want to invest.

Thanks.
